CEMENT MASON FALLS 2006-2008


FALLS

Falls are a major source of Cement Mason injuries, but they are preventable!

7Accidents are preventable!

FALLS FROM PLATFORMS

• CHECK THE GROUND CONDITION– Too firm or too soft?– Frozen? It might thaw and begin to

sink.

• Is the base of the scaffold or lift level?

• Is it supported on proper adjustable stands?

• If it is a rolling scaffold, are the castor locks in good working order and locked when not being moved?

RULES FOR SCAFFOLDS AND LIFTS


RULES FOR SCAFFOLDING• Scaffolding must be able to support at least four times

its intended load

• Anyone working in the vicinity of the scaffolding or on the scaffolding must wear a hard hat

• Anyone constructing or operating scaffolding must be certified 9Accidents are preventable!

RULES FOR SCAFFOLDING

• Scaffolding platforms must be kept as clear as possible

• Do not use scaffolding in bad weather conditions like high winds, snow or icy conditions


RULES FOR SCAFFOLDING and LIFTS

• Never remain on the scaffold when it is being moved

• Must be checked daily

• If moving, secure all tools and materials


Use a hoist to haul tools, equipment or any loads up to and down from the scaffold.

Keep both hands free for you

11


• Safe access to the scaffolding must be provided --avoid the need to climb over cross bracing.

RULES FOR POWER LINES: NOT JUST FOR SCAFFOLDS


REVIEW: SCAFFOLD RULES• DO NOT use damaged or distorted parts on any scaffold. • DO NOT allow anyone to be on scaffolds when they are feeling weak, sick, or

dizzy. • DO NOT work from any part of the scaffold other than the platform. • DO NOT alter the scaffold or any of its parts. • DO NOT move a scaffold horizontally while workers are on it, unless it is a

mobile scaffold and the proper procedures are followed. • DO NOT allow employees to work on scaffolds covered with snow, ice, or other

slippery materials. • DO NOT erect, use, alter, or move scaffolds within 10 feet of overhead power

lines. • DO NOT use shore or lean-to scaffolds. • DO NOT swing loads near or onto scaffolds unless properly controlled by a tag

line(s) -- and the load does not exceed the scaffold’s capacity. • DO NOT work on scaffolds in bad weather or high winds unless you determine

that doing so is safe. • DO NOT use ladders, boxes, barrels, or other makeshift contraptions to gain

additional height on your work platform. • DO NOT let unused or scrap material accumulate on the platforms. • DO NOT put more weight (including you) on a scaffold than it is designed to

hold.15Accidents are preventable!

What prevents the

lift wheel from falling

into the hole?



FALLS TO WORK SURFACE

Caused by slipping, tripping or falling while walking or working:

• On unstable, loose or uneven, or oily surfaces

• In slippery, wet , or muddy conditions

• By tripping over obstacles, objects, materials or scrap

21

What’s wrong here? Name the obstacles.


KNOW WHERE YOU ARE AT ALL TIMES

• Know your surroundings when walking – Be aware of tools and materials in walking/working areas,

especially pneumatic or electric tools with hoses and cords


FALLS FROM LADDERS

• Keep manufactured and job-made ladders in good condition

• Inspect ladders beforeeach use. Look for broken rungs or other defects. Destroy or repair defective ladders.

• Place ladders at the proper angle (1 foot out from the base for every 4 feet of vertical rise) 23Accidents are preventable!

Secure ladders near the top and/or at the bottom to prevent them from slipping

24

What’s wrong here? Is this safe?


FALLS FROM LADDERS

Building it on site?Make it safe!


http://www.ratemyeverything.net/image/10707/2/Ladder_Safety_101.ashx�

FALLS FROM LADDERS

• Extend ladders at least 3 feet above the landing to provide a handhold and for balance when getting on and off the ladder from other surfaces


Use a hoist to move materials and equipment.

KEEP BOTH HANDS FREE FOR YOU

FALLS FROM LADDERS


FALLS FROM LADDERS

• Use ladders only for what they were made – DO NOT USE as a platform, runway, or as scaffold planks.

• Always face the ladder and maintain 3 points of contact when climbing a ladder

• Do not set up a ladder near passageways or high traffic areas where it could be knocked over.


Does your ladder placement mean a fall PAST other safeguards?


FALLS SAME LEVEL• Wear the proper foot gear.• Walk slowly and never run on slick

ground.• Test potentially slick areas by

tapping your foot on them.• Keep walkways clear of water, ice,

oil and slippery materials.

30

• Watch for tripping hazards.• Always be sure that you can see over your

load.• Keep your eyes on where you are going.

FALLS SAME LEVEL


FALLS SAME LEVEL

• Avoid tripping hazards

• Any change in elevation is a major source of tripping.– Even a change of ¼ - ½ “ can

cause a trip.

– Curbs, cracks, single steps are all hazards.

• When these helpful hints don't work, and you know you are going to slip, try to reduce your potential injury when falling by:• Roll with the fall.• Relax as much as possible when you begin to fall.• Toss the load you are carrying. Protect yourself instead of the

objects being carried.


• Prevent or mark jutting material that may not be seen when walking quickly or with vision obscured (carrying materials or tools)


FALLS AGAINST OBJECTS


What’s missing here?

• USE REBAR CAPS AND GUARDS




MAYBE JUST ONE WILL DO?




What are the hazards in this picture? Are they corrected?

FALL AGAINST OBJECTS


FALL AGAINST OBJECTS

THOSE MUDDY BOOTS COULD NEVER SLIP, RIGHT?


What is missing here?

FALLS TO LOWER LEVEL

• Install guardrails around openings in floors and across openings in walls when the fall distance is 6 feet or more – Make sure top rails can

withstand a 200-lb load – Construct guardrails

with a top rail approximately 42” high and with a mid-rail about half that high (21”)

Floor and Wall Openings



• Cover all floor openings larger than 2” x 2”with material that can safely support at least twice the anticipated working load

• Secure and mark the cover



• There is no excuse for not covering and securing and marking every floor and roof opening, regardless of size

• It’s actually better to build a guard rail around the opening so that it can be seen


FALLS INTO OPENINGS

HOW MUCH PROTECTION DOES CAUTION TAPE PROVIDE? 44


HOW MUCH PROTECTION IS THIS BARRIER PROVIDING?


FALLS FROM VEHICLES• Step - don't jump - from vehicles or equipment

• Do not board or depart any vehicle or equipment that is moving• Watch where you park!


FALLS FROM STAIRS

• Do not store materials on stairways

• Keep hazardous projections (such as materials, protruding nails, large splinters, etc.) off stairs, treads or handrails

• Correct slippery conditions on stairways before they are used


FALLS FROM STAIRS

• Keep all cords, hoses and welding leads off the stair treads and risers

• Keep stairs clear of debris


Could you see this hazard?

PREVENT TRIPPING• Keep walkways and stairways clear of trash and

debris• Keep boxes, scrap lumber and other materials

picked up


How many ways to trip can you see?

PREVENT TRIPPINGWHAT COULD YOU DO? OR DO BETTER?


PREVENT TRIPPING

• Keep tools and supplies out of traffic areas

• Provide enough light for workers to see and to prevent accidents

STRUCK BY/AGAINST

Struck by/against: • impact of a part of the body against something or • hit by a moving or flying objects• or by noise (noise impacts the ear drum)

When a worker is • hit by work tools, • by construction materials, • by a vehicle, by equipment

such as a backhoe bucket, • by flying debris, • by earth during a trench

collapse, or • by any other object


STRUCK BY/AGAINST

• Never work under a vehicle or equipment that is supported only by a jack or stand. The jack or stand could tip, and the raised equipment then will be dropped on the person under it.

• When helping someone to hitch equipment or an implement to a truck or tractor, stand to the side. That way, the driver can see you. Also, you won’t be between the truck and the equipment.

CAUGHT IN & CAUGHT BETWEEN

Reasons Caught-In and Caught-Between Accidents Happen

• Working on moving equipment

• Working under mental or physical stress

• Using unsafe equipment

• Lack of training or instructions

• Inadequate guarding on machines

• Incorrect hitching practices

• Distraction

CAUGHT IN/UNDER/BETWEEN - a part of the body is squeezed, pinched or crushed in machinery or materials


CAUGHT BETWEEN


CAUGHT BETWEEN• Never assume that the driver of a vehicle or

equipment operator SEES YOU.

• Vehicle and equipment operators must always look in the direction of travel.


CAUGHT BETWEEN

• Always install safety locks or other safeguards before getting under or between two objects that have the potential of trapping you.

• While unloading or working on equipment, the wheels of equipment need to be pinned to hold them stationary. – This procedure is called chocking. Position chocks to prevent vehicles

from inadvertently moving in any direction.

CAUGHT IN/BETWEEN• Safeguard against contact with moving

machine parts.

• Shut off power, perform lockout/tagout, and release any remaining energy before unjamming, servicing, lubricating, or adjusting machinery.

• Replace guards after servicing and before resuming use of equipment.


Avoid wearing jewelry and tattered or loose clothing around machinery, and wear hair short or tucked inside clothing
